The PicoScope 4000A Series of PC oscilloscopes is a second-generation upgrade and expansion of our high-resolution, deep-memory product portfolio.

With 2-, 4- and 8-channel models available, the PicoScope 4000A Series boasts 12-bit hardware resolution (to 16 bits with Resolution Enhancement), 256 MS deep capture memory, 20 MHz bandwidth with 80 MS/s sampling speed, up to 70 dB SFDR and a built-in 14-bit triggerable signal generator and 80 MS/s AWG. A SuperSpeed USB 3.0 interface powers the instrument and delivers up to 160 MS/s communications to the host PC.

All models run with the popular PicoScope user interface and benefit from the free PicoSDK software development kit, which gives users direct programming control of the hardware for custom applications. The scopes also work with PicoLog 6 data logging software for lower-speed long-duration captures.

The following features come as standard on all 4000A oscilloscopes:

Complex embedded systems

When debugging an embedded system with a scope, you can quickly run out of channels. You may need to look at an I²C or SPI bus at the same time as multiple power rails, DAC outputs and logic signals. With up to eight channels, the PicoScope 4000A Series can cope with all of this. Choose whether to decode up to eight serial buses, with analog waveforms and decoded data both visible, or a combination of serial buses and other analog or digital signals. PicoScope provides advanced triggering on all channels, so you can search for runt pulses, dropouts and noise as well as looking for data patterns using the 4-input Boolean logic trigger.
